 * @extends Ext.state.Provider
 * A Provider implementation which saves and retrieves state via cookies.
 * The CookieProvider supports the usual cookie options, such as:
 * &lt;ul&gt;
 * &lt;li&gt;{@link #path}&lt;/li&gt;
 * &lt;li&gt;{@link #expires}&lt;/li&gt;
 * &lt;li&gt;{@link #domain}&lt;/li&gt;
 * &lt;li&gt;{@link #secure}&lt;/li&gt;
 * &lt;/ul&gt;
 &lt;pre&gt;&lt;code&gt;
   var cp = new Ext.state.CookieProvider({
       path: &quot;/cgi-bin/&quot;,
       expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
       domain: &quot;sencha.com&quot;
   });
   Ext.state.Manager.setProvider(cp);
 &lt;/code&gt;&lt;/pre&gt;
 
 
 * @cfg {String} path The path for which the cookie is active (defaults to root '/' which makes it active for all pages in the site)
 * @cfg {Date} expires The cookie expiration date (defaults to 7 days from now)
 * @cfg {String} domain The domain to save the cookie for.  Note that you cannot specify a different domain than
 * your page is on, but you can specify a sub-domain, or simply the domain itself like 'sencha.com' to include
 * all sub-domains if you need to access cookies across different sub-domains (defaults to null which uses the same
 * domain the page is running on including the 'www' like 'www.sencha.com')
 * @cfg {Boolean} secure True if the site is using SSL (defaults to false)
 * @constructor
 * Create a new CookieProvider
 * @param {Object} config The configuration object
